It has something to do with time synchronization. I have other servers and got notified that the time on one of those servers was off...
Then I checked every server and noticed that the cargame server also had no active time synchronization. Activated that.. But apparently LFS does not like that.
Lesson learned.
* That the S2 server was not there for an hour had nothing to do with it. I heard everybody was driving FBM again and switched S2 completely off. Still don't know what the problem is btw. Some bug in Airio, sure of it (car config line too long).
This was a bad day for me anyway. Shitload of problems, got pissed off
